Convolutional neural networks, or CNNs, are distinguished from other neural networks by their superior performance with image, speech, or audio signal inputs. But how exactly do they work?
In this lightboard video, Martin Keen with IBM, explains how this deep learning algorithm operates to enable machines to view the world as humans do.

Mans just wrote in perfect handwriting BACKWARDS on the glass and no one is talking about it what the heck
um actually the video
is mirrored
The magic of video editing, he’s a wizard
If you look around, you'll find a video they made to address just this question, everyone who watches IBM videos asks exactly that, I know I did :)
Unbelievably clear and succinct explanations
Thanks for the appreciation, Sunny, that's what we strive for! 🙂
Well said

Bro this dude just wrote mirrored wth. Also thanks for the video! The concept of CNN is a lot more clear to me now. :))
Glad this was useful to you! 👍 As for writing mirrored, here is how we do it 👉 ibm.co/3jnq1st 😉
Amazing explanation!
Two quick questions:
1. If each layer of a neural network can recognize more complex / abstract objects, does that mean that deeper neural networks (neural networks with more layers) will always be more powerful, or at least have the potential to be more powerful?
2. Could one say the same about the width of neural networks? Would a neural network with more nodes per layer be able to recognize a larger variety of images?
Explained in a very simple way that's easy to understand! Great video!
Have been watching several videos to get a high level understanding of CNN, but no luck. However, this is a very good explanation ! Cleared lots of doubt in few minutes. Thank you
This is too low level and vague for people who need it and too high level and complicated for children, I believe that you should go more in depth to provide more information such as how the convolution works, different activation methods and different types of layers
It is just an introduction. If one wants to learn the details, they can search for textbooks, I believe there are countless available.
Then actually go and study CNNs. This is a brief overview of how they work.
These videos are for 2 demographics, young adults/teenagers who find AI technology fascinating and want to understand how it works. And for children to spark the flame of the scientist inside them towards AI development when they grow up. The Second reason is the most important.
I genuinely needed a 2 minute explanation of this term and a few others. I guess I'm the target audience.
The intro just rocked, as to why CNN. "Humans can do object detection quickly and machines can't" and hence that's where it begins. Amazing... Thanks...
0:42 I cannot get over the fact that this dude just wrote the term CNN backwards so easily and so fast :O
Or maybe he just inverted the video horizontally in post edition
try looking at the video using a mirror ...
He inverted the video. That's why he's writing with his left hand and wearing his clock on the right arm.
@@badbud804yeah, I also mentioned that but it would be very impressive if he could actually do that
I don’t like CNN.
Oh… one moment… wrong video.
man i like how you clearly explain your videos
In my eyes , the goal of Convolution is to make the signal invariant to scaling and translation. It acts as a pre-processor of the raw input signal. You could also first pre-process your training set and store it in a file. Then you can use this file and feed it directly to the deep neural network. You don't need the Convolution anymore at training.
Another way of making your signal (picture) invariant is to first Fourier Transform it to make it scaling and translation invariant. Next you transform the signal from cartesian to polar coordinates to make it rotational invariant. Finally you Fourier Transform that signal and end up with a fully invariant signal that you can store as a pre-processed Training set.
Any citations for elaborating what you said.
But CNN makes it possible to sequentially apply more abstract filters that fit the specific objects in the image. I'm not sure if those transformations you named are able to do that, which is taking very complex and abstract patterns into account.
Such a likeable person explaining so well, much appreciated! :)
Machine learning is truly amazing yet it pales into insignificance when compared to the ability of this chap to write backwards.
I cant tell whether you're joking, but I think the video is flipped horizontally
Martin, how are the filters for a CNN created? Random? stored in some database? Might there be advantage from specifying filters yourself, particularly if you have expertise with the domain the images are from ?
Identifying, organizing and reaping to thought.
Your tv CAN communicate with you via your neurons producing electromagnetic waves
certo, curiosidade: Se tratando de pessoas gêmeas ou sei lá trigêmeas univitelinos como diferencia-las pela CNN? Outro detalhe com relação aos filtros, suponhamos que temos objetos sobre as retas por exemplo como identifica-las neste processo com tão vastas imagens possíveis de armazena-las?
Well if the beer videos ever stop Martin you have a career in IT Vlogging 😁
Is he writing backwards...! impressive
No, obviously.
Hi! Have I assumed correctly that in case of using CNNs for image recognition, the deeper the filters go, the more they zoom out on the image?
Next logical question is - what type of software is used to analyze test cases (e.g. real houses) and create those filters?
The filter is no more than just a matrix. The discrete convolution is performed in each layer (this is where the name CNN comes from). The filter is refined using training data, just like how you would train a perception, you train the matrix to behave as desired.
Anderson Nancy Johnson Ruth Williams Deborah
So I take the key to building a CNN is on how to build the filters? also, given that the first layer is fragmented, does it mean that the first layer could be of general usage, while the later layers are more application oriented?
there should be a full course on this neural network taught by Martin
Jackson Jennifer Martinez Thomas Thompson Michael
so by combining the other video of yours. At the end of the the CNN there will be a discriminator which has been trained to know what a house looks like, what an apartment looks like, what a skyscraper looks like and therefore tells you that is a house ?
Moore Larry Thompson William Gonzalez Betty
It's just like our brain recognises objects. Can we make conscious using this technique? Probably yes in future
Fantastic Video. Is Martin always writing mirrored? I am fastinated by how your video recording works!
This channel has some of the best CompSci explanations ! Never been disappointed!
Doesn't it require a lot of manual work to make all those filters? Isn't it better to just run everything through a regular neural network?
Wilson Thomas Martin Barbara Jones Jeffrey
Application of successive Convolutional Filters well presented but at a high level only
Miller Mary Wilson Joseph Williams Jeffrey
Wait, that's a house? I thought it was the head of a tin robot.
you are more and more better than my clg faculty thank you for a great a explanation 😍
Hello, thank you for the explanation but I still don't understand how the filters are made.
This is probably the best explained video i've ever watched, you're a great tutor!!!!!😍😍
What would be the difference between the standard convolutional networks and something newer like CLIP?
this video hits different if you are currently taking digital image processing course. I feel smart lol
Hi ,I'm a maths student and I need to do a project. the theme is games and sport. I saw your video and thought why not apply this technique to the world of sports? to discover from the analysis of the players' movements if one is sick. Can you help me to apply CNN and use it well please.
Don't ask him. His explaination is sloppy and incomplete. The convolution operations with the filters produce matrix channels building the tensor. For example after four convolution operations, you should have four matrix channels. The next operation would be a max pooling operation on each matrix channel in the tensor. Please let me know if you have a question.
At last a video that is useful!
I have a question how are the levels of filters are defined ?
love this explanation ...
Very good explaination. Thank you.
Can we implement this CNN to determine micro-level profiles, i.e., micrometer level?
clear and concise bigger picture of CNN
that was a simple wow,,,,
Fantastic explanation! Very pedagogical and easy to follow. Thank you!
Dear lord this is perfectly chunked information.
Realising you are a children is good thing
Terrible explanation
Thanks. Great learning Video.
Wht a explanation
Martin, you are a superb teacher. You make learning easy and fun.
best teacher!! 👏
Edmond Prairie
Thank you :)
Funny guy. Love him
Clifton Well
is this what the vision pro uses?
The volume is a bit quiet here.
Very excellent explanation ❤
thanks
ily
You made it easy to understand. Very helpful. Thanks a lot :)
What kind of bord do u use to write
See ibm.biz/write-backwards
Nice series Marvin 😁
This explanation was so good. Currently using CNNs for remote sensing applications.

can you help me regarding my project "human pose estimation"
Hi Rasel! What sort of help would you need? 🙂
@@IBMTechnology i have to detect human pose estimation through skeletal data extracted from it
Thank you
amazing as usual.
clearly understandable 🙏🙏🙏
This was easy to understand and very concise...Thank you
Very clear and right-to-the-point explanation! Thank you!
Will the Activation Functions video come?
👍
perfect explanantion. I hate it when people throw difficult terms around. Why can't it be precise and clear such as using a house as an analogy. Well done!
lol u work in garage and u want teach us
Awesome explanations ! ... thank you for sharing your knowledge ;))
Explained this video very well - highly recommend! Thank you
Most worst and incomplete explaination and diagrams that I have seen so far for a beginner video. Their is nothing cool about what he did or said. No beginner could do it by this explaination. For example, he said the filters are combined; but they are not combined. Maxpooling is done on the result of the convolution operation only to reduce the size of the image only and this is done only to reduce the number of inputs to the next convolution layer or the inputs to the fully connected neural network for classification.
All I can think of is... that how good he is in writing everything mirrored....
oh my god, thankyou for the explanation. Easy to understand
such an easy, clear and to the point explanation! thanks a lot
This guy gives crystal clear explanations. Supremely Clear!
Great video 🔥
